Dear Friends,
I'm sorry about my previous answer. COMP-3 is always
efficient.
when COBOL uses COMP, it tries to align fields along
boundaries which is less efficient in retrieval and
computation.

Answer / praveen
when ever the data size is at higher boundries comp is best.
when ever the data size is at lower boundries comp-3 is
best.
lower boundries higher boundries
s9(01) s9(04) 2 bytes
s9(05) s9(09) 4bytes
s9(10) s9(18) 8bytes

Parry , While using COMP , the data can be retrieved
quicly , that is the advantage os storing data along word
boundaries .

Answer / praveen
for comp3 the caluclation of memory goes
for the datasize is even we go for formula n/2.
for the datasize is odd we go for formula n+1/2.
ex; s9(5) means 5 is odd 5+1/2=6/2=3
it takes 3 bytes of memory.
for comp s9(9) it takes 4 bytes of memory.
so here depending on the datasize we can say the
best.
so in above ex; we say comp3 is best because there is a
supression of memory i.e 3bytes compared to comp 4 bytes .

In terms of Storage, it will be comp-3 and for Arithmetic
computations, it will be comp
